refactor(lab): phase 3 — token purification across lab.html / lab.css / lab-glue.js
Replaced ~100 hardcoded brand colors with var() tokens across 3 files.
Kept: tinted-alpha colors (rgba(155,93,229,.x)), canvas fillStyle (vars
don't resolve there), curated SVG card-preview palettes (P_GRAPH, P_MAGNETIC,
etc.), physics-convention colors (#EF476F for positive charges, #4CC9F0 for
negative), slightly-different decorative shades (#EF476F ≠ #F15BB5).
lab.css: #9B5DE5→var(--violet), #06D6E0→var(--cyan), #F15BB5/nscene→var(--pink),
#0F172A (filter.active)→var(--text), fn-color defaults, trig btn defaults.
lab.html: stat bars, slider labels, info-fn-dot, toggle-dot, panel badges,
section-specific color coding (violet=wave1/param1, cyan=wave2/param2).
lab-glue.js: toggleTheory() JS style assignments, template-literal HTML headings.
Before: ~265 hardcodes After: ~60 (canvas+curated+rgba+physics-convention)
